实现and与or查询——elasticsearch

{
	"query": {
		"bool": {
			"must": [{
				"match_phrase": {
					"name": "a"
				}
			}],
			"should": [{
				"match_phrase": {
					"city": "b"
				}
			},
			{
				"match_phrase": {
					"city": "c"
				}
			}],
			"minimum_should_match": 1
		}
	},
	"size": 5
}

实现 "name"=="a" and ("city" == "b" or "city" == "c")
